That’s straight up not true. It’s not even remotely close to that.

If you’re getting a segfault in C++, it’s also cause you used unsafe code. It’s just not officially enclosed in an “unsafe” block.

The whole point of a segfault is that you can’t really know anything about it. Even in rust, when you get a segfault there is no meaningful error.

The lightsaber orientation is the same as the slash orientation

Which is exaxtly what I said, that it’s fast enough for most use cases.

In theory though, you will “gain performance” by rewriting it (well) in C for literally anything. Even if it’s disk/io, the actual time spent in your code will be lower, while the time spent in kernel mode will be just as long.

For example, you are running a server which reads files and returns data based on said files. The act of reading the file won’t be much faster, but if written in C, your parsers and actual logic behind what to do with the file will be.

But it’s as you said, this actual tiny performance gain isn’t worth it over development/resource cost most of the time.

How are they ignorant? It’s a known fact that java is slow, at least slower than some others. Sure, it’s still fast enough for 95% of use cases, but most code will run faster if written in, say, C. Will have 10x the amount of code and twice as many bugs though.

Back in my day people worked 16h days everyday and had no time for math or computers. And that was JUST FINE.

Which is fine, only it might confuse whoever then has to maintain your code.

n is genrally the max though. “From i=0 to n” is used in math all the time.

Or at least run it in the test database first.

Or run your updates/deletes as select first.

If you’re using X11, you can use xkill: https://en.m.wikipedia.org/wiki/Xkill

You can bind it to a key in gnome/kde (not sure how they handle custom keybinds. Otherwise add a call to xbindkeys to your .bashrc or equivalent). It kills any window you want, responsive or not.

As for the terminal, I don’t think you can send SIGKILL, but ctrl + \ will result in a core dump if you’re using bash.

Is there any reason to use :w other than it being the default? I have mine mapped to CTRL-S and it makes sure to keep me in insert mode if I was in insert mode. Feels way faster and easier to spam than the 4 key presses it takes to execute “:w”.

Most websites use them. Smaller file -> less bandwidth -> lower costs.

I assume they wrote it as 5000 and it got changed to 5E3 by the minifier as it saves a byte?
